TVA letter to NRC dated February 25, 2011, Watts Bar Nuclear Plant (WBN) Unit 2 - Final Safety Analysis Report (FSAR) - Response To Chapters 11 And 12 Request For Additional Information This letter transmits WBN Unit 2 FSAR Amendment 103 (A103), which reflects changes made since the issuance of Amendment 102 on December 17, 2010 (Reference 1). This amendment includes changes to Sections 9.1 and 2.4 previously provided via References 2 and 3. In Reference 4, TVA committed to provide Chapter 11 updates in response to NRCs request for additional information. However, since that time, additional Chapter 11 questions have been received from the staff. Therefore, A103 does not contain any Chapter 11 updates but remains unchanged. Instead, TVA will provide an advance version of Chapter 11 along with answers to the remaining RAI questions in separate correspondence. If found acceptable by the staff, final Chapter 11 updates will be provided in A104.

1. Within FSAR Section 9.1.3.1.1 on page 9.1-5 (A101),

replace the 3rd, 4th, and 5th sentences with Insert A below:

Insert A - Under design basis Ultimate Heat Sink (UHS) temperatures and heat exchanger fouling conditions, the heat load in the spent fuel pool is limited to 28.1E+06 BTU/hr during refueling outages. Under more favorable conditions, up to 50.2E+06 BTU/hr may be accommodated. Cycle specific calculations may be performed prior to the start of a refueling outage to determine the exact heat removal capability of the SFPCCS using recent heat exchanger performance testing and anticipated UHS temperatures; otherwise, 28.1E+06 BTU/hr may not be exceeded. The rate of fuel transfer from the reactor to the SFP is controlled such that, with one (1) train of SFPCCS in service, the SFP temperature will remain below 151.2 °F.

2. On page 9.1-10 (A101), replace the last sentence of the first paragraph with Insert B below:

Section 9.1.3.1.1

1. Section 9.1.3.3.3 2-103-01 Insert B - Following unit shutdown, a decay time of Table 9.1-1 approximately 33 days prior to the completion of core offload is required to maintain the total SFP decay heat below 28.1E+06 BTU/hr design basis limit.

3. On page 9.1-10 (A101), replace the first sentence of the second paragraph with Insert C below:

Insert C - For full core offload following a normal refueling outage (Emergency Offload), it is assumed that a unit is required to shutdown 36 days after a refueling outage on the opposite unit. Following shutdown, it is assumed that core offload will be completed after a 60 day decay time.

Under these conditions, the maximum SFP decay heat will be less than 25.61E+06 BTU/hr, which is less than the normal refueling case.

4. On page 9.1-10 (A101), replace less with better in the second sentence of the second paragraph.

5. Replace Table 9.1-1 with new table.

Pressurizer and reactor vessel nozzle dissimilar metal (i.e.,

Inconel Alloy 82/182) are susceptible to stress corrosion cracking. Under sustained tensile stresses, dissimilar metal (DM) nozzle buttering and nozzle to safe end butt welds can develop cracks through corrosive action of the primary water.

19 5.5.3 However, stress corrosion cracking does not occur in materials 2-103-19 that are in a compressive state of stress. Therefore, TVA has committed to industry guidance document, Nuclear Energy Institute, (NEI) 03-08, Guideline for the Management of Materials Issues, to address these materials issues. NEI 03-08 endorses MRP-139, Revision 1, Material Reliability Program: Primary System Piping Butt Weld Inspection and Evaluation Guideline.

Number Under this program, TVA has used Mechanical Stress Improvement Process (MSIP), a proprietary mechanical process, which mitigates and prevents the initiation of stress corrosion cracking at dissimilar metal (DM) weld locations in components and piping. The process works by generating beneficial compressive residual stress patterns from the pipe inside surface to about halfway through the wall thickness in both axial and circumferential directions. The resulting compressive residual stresses prevent crack initiation and arrest existing shallow cracks. The process is accomplished by a one-time application of compressive force and mechanically controlled permanent radial contraction to the outside surface of the nozzle safe end and/or piping. A split clamp ring is placed around the nozzle safe end and/or the attached pipe or elbow at a specified distance from the DM butt weld centerline. The gaps between the clamp ring halves are shimmed and then the clamp ring is contracted by box presses (i.e., framed hydraulic cylinders) to circumferentially compress/yield the piping within the specified range. The MSIP box presses and clamp ring are then removed from the piping.

MSIP was applied to prevent stress corrosion cracking of the nozzle buttering and nozzle to safe-end butt welds on the six 19 pressurizer nozzles, the four reactor vessel cold leg nozzles 5.5.3 2-103-19 (cont.) and the four reactor vessel hot leg nozzle locations. The Unit 2 pressurizer spray, safety and relief nozzles and the Unit 2 pressurizer surge nozzle had the MSIP clamp ring placed directly on the nozzle safe ends. For the Unit 2 reactor vessel nozzles the MSIP clamp rings were placed on the hot leg pipes and the cold leg elbows.

MSIP was applied as a special process under ASME Section III for Unit 2. QA requirements for Control of Processes are defined in ASME NQA-1, Quality Assurance Requirements for Nuclear Facility Applications. ASME NQA-1 is invoked by both ASME III and ASME XI. The ASME NQA-1 requirements were met by the Westinghouse and Unit 2 certificate holder PCI Energy Services NPT/NA ASME QA Programs.

Addenda to the pressurizer and reactor vessel component and piping stress reports of record were prepared by Westinghouse and TVA to present results of the re-analyses and reconciliations performed to evaluate the effects of MSIP and to demonstrate that the stress reports of record remain valid.

These addenda confirm that the deformed geometries of the component nozzles and piping including elongation do not have any adverse impact on the existing ASME Section III stress qualifications of record.
